v1.1.0 — live controller status

Minor release on top of v1.0.1.

New: live controller status

• The config page now shows a status card at the top: whether a controller
  is connected, its model (DualSense / DualSense Edge), and a battery gauge
  (percent + charging indicator), refreshed every few seconds.
• Served from a read-only GET /api/status endpoint, so any client can poll
  it — this is the intended foundation for a future Decky Loader plugin that
  would surface the same status in the Steam Deck Quick Access Menu, in parallel
  with the web page (no firmware changes needed for that).

(RSSI was evaluated and intentionally left out: over Bluetooth Classic the
controller's HCI RSSI is relative to the Golden Receive Power Range and reads ~0
in normal use, so it isn't a useful signal-strength number.)

No other changes from v1.0.1. See the
v1.0.0 notes
for the full feature list.
